The square cup test is a method used for the determination of sheet metal forming properties.
The square cup punch and deep drawing tools punch blanks from metal strips, and deep draw cups with square bases. The test is also used to test coating adhesion (e.g. punch/stamp coating, coil-coating zinc, etc.)
